Abstract

Nail gun (1) comprises barrel (23) and loading mechanism (20) for loading nail from magazine (19) into muzzle (14). Nail (3) is adapted to be propelled by punch (16) via piston shuttle (7) movable by a gas propellant that is initially stored as a liquid in reservoir (2). The liquid is heated to a super critical state in high-pressure chamber (4) by heating element (5) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel nail (3) from muzzle (14), regardless of the ambient temperature. The propellant is preferably CO2 which is heated to 31.06 DEG C. Pressure selector (9) allows for different pressure settings suitable for softwood, hardwood and masonry nailing applications. Gun (1) produces minimal noise and so reduces workplace noise pollution.

Description of drawings
The present invention will be described with reference to the accompanying drawings for the general, wherein:
Fig. 1 is the schematic elevational view according to the ail gun of one embodiment of the invention, and wherein, a nail just penetrates from this ail gun.
The specific embodiment
Fig. 1 has described an ail gun 1 of one embodiment of the invention.This ail gun 1 is a kind of handheld tool that is used in carpentry and the building industry.
This ail gun 1 comprises the liquid CO 2 (CO of a 250cc 2) holder 2, this liquid CO 2 is converted into as " supercritical fluid " or " high concentration gas " that break out the energy to release or to penetrate nail 3 by phase transformation.This ail gun 1 comprises a high-pressure chamber 4, liquid CO 2Produce phase transformation therein and be converted into high concentration gas.This high-pressure chamber is communicated with a gun barrel 23 fluids by a gas shut-off valve 24.By the first 5 couples of CO of heating member that power by its size and shape and the similar battery pack 6 of traditional no electric wire electric drill battery pack 2Heating.In this embodiment, the piston slider 7 that is arranged in bore 8 passes through jumper bar 16 with CO 2Outburst can mechanically pass to the nail 3 that is launched.Ail gun 1 is provided with one and for example has the pressure-regulating device 9 of three class different settings between the maximum of minimum of a values to 1350 crust of about 35 crust so that be applicable to various thing such as cork (low pressure), hardwood (middle pressure) and the masonries (high pressure) followed closely.This pressure-regulating device 9 is operably connected on the electronic control unit (ECU) 10, and this electronic control unit control and adjusting are transported to the CO of described chamber 4 2The supply of propellant and pressure and this CO 2The heating of propellant.
Work as CO 2When being heated to 31.06 ℃, it becomes a kind of " supercriticality " that becomes " supercritical fluid " or " the high concentration gas " of high pressure.In this embodiment, regardless of environment temperature, CO 2Critical condition when liquid phase becomes gas phase provides and released the required outburst energy of described nail 3 from this ail gun 1.
Following table has illustrated liquid/gas CO 2Temperature/pressure relation.
Temperature (℃) pressure (crust)
21 54
31 74 critical points
100 250
500 1250
1000 2500
Can understand CO by following content 2Suitability as preferred propellant:
1. under 25 ℃, 1 restrains liquid CO 2To be released to 500cc gas;
2. under 25 ℃, 1 restrains CO 2=0.759cc (1 gram CO 2Volume be 0.759cc);
3. under 25 ℃, 1cc liquid CO 2To be released to 660cc (gas).
The major advantage of this ail gun 1 is, it can substitute three kinds of rifles of all above-mentioned prior aries by its adjustable pressure device, and it is lighter and be easier to operation than traditional ail gun.For this ail gun of operation in different application, need to regulate the nail of a selector to obtain required pressure and to be fit to according to desirable application coupling.
The internal gas holder 2 of 250cc will be enough to provide about 1500 low pressure nailings, or injection nail in about 1000 times, or about 500 sub-high pressure nailings.
The sound of firing that can hear is low especially, thereby helps to reduce the noise pollution of workplace.
The advantage of this ail gun 1 is, can obtain and be easy to control propellant-liquid CO easily at gas outlet 2In order to load this holder 2 again, the operator is connected to a little easy-operating liquid CO by a high-voltage tube with this rifle 2On the tube.Be arranged on the liquid CO that holder 2 in the rifle 1 is equipped with about 250cc 2
For example be applicable to that with one a box nail of cork is fixed on this rifle.Then select the low pressure setting.Make this ail gun 1 open insurance by the switch 12 on the bottom of this small of the stock 13 subsequently.This ECU10 makes small amount of liquid CO then 2Be discharged in the chamber 4.By this ECU10 monitoring temperature and pressure.
The muzzle 14 of this ail gun 1 is pressed against on the material to be fixed.It is safe that a pressure inductor (not shown) in this muzzle 14 points out described ECU10 ail gun 1 to fire.The operator pulls actuated triggers 15.After the time delay in a second, this ECU10 operationally controls heating element heater 5 with the CO in the heated chamber 4 2Thereby, cause that phase transformation makes CO 2Be converted into " high concentration gas " and its pressure is increased.Should " high concentration gas " be discharged in the gun barrel 23 by valve 24 then, thus propelling piston slide block 7.This piston slider 7 clashes into jumper bars 16 and drives nail 3 and passes work materials.Simultaneously, the restriction jumper bar 16 that is suitable for clashing into nail 3 is gone out muzzle 14 to avoid it.When jumper bar 16 and piston slider 7 arrived its strokes terminal, the lid of opening an initial exhaust outlet to be to collect some high pressure exhaust gas and be stored in the exhaust accumulator 17, then, and main vent 18 release waste gas.In case gas is discharged from, piston slider 7 and jumper bar 16 are just put by the round robin start bit that a spring mechanism (not shown) turns back to them.One auxiliary exhaust mouth (not shown) is combined in the valve 24 and by trigger 15 and operationally starts to discharge gas from described bore 8.This allows sliding the determining of piston 7 to turn back to round robin start bit fully and put.When the pressure from described muzzle 14 reduces and actuated triggers 15 when being released, utilize the waste gas that is stored in the described accumulator 17 from nail box 19, to load a new nail 3 to rifle again by a pneumatic mechanism 20.Can in the time cycle in about two seconds, repeat this step.
Because can obtain much higher pressure, thus in this design, use the cylinder/bore of minor diameter, thus reduced the overall dimensions and the weight of ail gun.
Preferably, high-pressure chamber 4 is made of metal, and still, the main body of rifle comprises gun barrel, can be made by metal, plastics or synthetic material.
In another unshowned embodiment, battery 6 can be substituted by some other external power supply.
In another unshowned embodiment, can be with CO 2Be initially stored in the removable holder, this holder can be a kind of container (not shown) that is different from the holder 2 shown in the foregoing description.This container can be that can recharge or disposable.
In another unshowned embodiment, be used to store CO 2Holder 2 or the capacity of the container 250cc that can be greater than or less than in the foregoing description to be mentioned.
Should be appreciated that, though owing to its characteristic and commercial availability are selected CO 2As preferred propellant, still, can in alternative embodiment, use other liquid state/gaseous propellant.
Terminology used here " comprises " and is used for that wide significance " comprises " or " having ", but not restrictive, sense " only by ... constitute ".
